The Australian Diamonds have continued their dominance in the Netball Quad Series after a narrow 53-50 victory over Tasman rivals the Silver Ferns.

Although the Aussies were missing veteran shooter and captain Cailtin Bassett, who broke her forearm during training, and wing defence Gabi Simpson due to a leg injury; New Zealand could not overtake the World Champions.

The damage was done in the first quarter in which a poor start had the Silver Ferns trailing eight goals behind. It took almost four minutes for New Zealand shooter Maria Falou to sink their first goal, and Ameliaranne Ekenasio only managed to mark the scoreboard during the final minute of the first fifteeen.

The Silver Ferns only began to close the gap after coach Noeline Taurua made crucial changes in the centre court and stuck with the rejigged seven for the remainder of the game.

While Laura Langman - who became the first New Zealander to reach 150 Test caps during the match - moved into the centre position, Karin Burger came on in wing defence and Samantha Sinclair moved onto the bench.

By halftime the Silver Ferns had only managed to take back one goal in the margin, but eventually came within six goals in the third.

The pressure forced Australian coach Lisa Alexander to bench shooter Stephanie Wood for Gretel Tippett in the third quarter, who went on to score 12 goals for the Diamonds at 100 per cent.

Although the Silver Ferns pushed to a two-goal deficit in the mid-way through the forth, the midcourt pressure by Liz Watson, Kelsey Browne and Jamie-Lee Price orchestrated the play to hold-off the New Zealand outfit until the final whistle.

"It was composure and patience," Jamie-Lee Price said after being awarded player of the match.

"The Ferns really brought it to us today and I'm really proud of the girls because we stuck to the way that we play, and we didn't let the pressure get the better of us."

The Diamonds will play the England Roses in a final showdown on Monday morning, 5am AEDT.
